HOW TO FIND THE RIGHT WEIGHT
Put your hair into a ponytail.
With your thumb and index finger, create the "okay" symbol tightly around the base of your ponytail.
Keeping your thumb and index finger in the same position, pull your ponytail through your fingers and take a look at the placement of your index finger.
